动词加s和ing的方法动词ing形式的用法及变化规则二.动词现在分词由动词原形在词尾加ing构成,其规则如下:1)一般情况下直接加ing think---thinking sleep---sleepingstudy---studying speak---speakingcarry---carrying say---saying2)以不发音的字母e结尾的单词,去掉字母e,再加ingwake---waking make---making come---comingtake---taking leave---leaving have---having3)以重读闭音节结尾,呈现“辅,元,辅”结构的动词,先双写末尾的辅音字母,再加ing初中学过的这类词有:begin,cut, get, hit, run, set, sit, spit, stop, swim, beg, drop, fit, nod, dig, forget, regret, rid, 等。

visit 不是以重读闭音节结尾,不用双写travel虽然重读第一音节,词尾音节不重读,但是现在分词仍要双写末尾辅音字母,然后再加ing ,如:travel---travelling.初中阶段此类词只有这一个。

4)以 y 结尾的动词直接加 ingcarry—— carrying enjoy—— enjoying5)以ie结尾的动词,把ie改为y ,再加ingdie---dying lie---lying动词第三人称单数的变化规则及练习一、变化规则1、直接在动词后+s例如:like- likes play-plays2、以s, x, sh, ch, 接尾的动词:+es例如:wash-washes3、以辅音+o接尾的动词:+es例如:go-goes4、以辅音+y接尾的动词:变y为i+es例如:fly-flies英语名词单数变复数的规则一、绝大多数的可数名词的复数形式,是在该词末尾加上后辍-s。
